Solid fuel boilers. Boilers long burning
One of the popular aggregates for creating a system of heating a private house remains a solid fuel boiler for long burning on firewood. It is especially convenient for heating a large building, to which it is impossible to bring the main gas.
Modern aggregates with a long-burning design are able to function offline for many hours, which simplifies the operation of the heating system. But in order to choose the right boiler, which will fully answer the needs of warm, it is necessary to at least approximately represent its device and the principle of operation. In addition, a lot of specific criteria is taken into account, which is also important to remember.
Why is the wood boiler sometimes becomes the best option?
Definitely optimal option Both the convenience of operation and the cost of the energy carrier, gas aggregates are recognized. But, unfortunately, not all settlements of the country (and especially concerns rural areas) covered by gasification. In addition, summing up the gas to the house, even if there is a central highway, is a rather difficult and cost-related task associated with the design of numerous documents. Getting all permits and coordination, project preparation, as well as the purchase of all necessary to summarize an individual gas supply line will require a lot of time, nerves, money.
Electrical heating units seemingly can be applied to heating any structure to which electricity was supplied. Such boilers are easy to install, adjust and operate. However, their use also has its own "pitfalls."
For example, to install high power devices (above 7 ÷ 9 kW) it is necessary to conduct a three-phase power line. And this is again campaigning on instances, project preparation, its coordination, approval and other "joy." Another factor that cannot be taken into account is the high cost of electricity, and every year it grows. Therefore, the payment for heating using an electric boiler can become a magnificent burden for the budget of the family.
In addition, it must be remembered that if during an emergency it will turn off the electricity, then the house will remain not only without light, but also without heating.
Login output - with the impossibility of using gas, a solid fuel boiler is more reliable and beneficial when heating a private house. Especially since housing heating for many decades is traditional, since there is no shortage of this fuel. Especially problems do not occur in regions rich in forest arrays, in which there is always enough dry. Yes, and buying ready-made firewood on the scale of the heating season will cost much cheaper than electricity pay.
That is why, even by installing gas heating equipment, very many old houses are not in a hurry to get rid of furnaces and fireplaces, which are supported in the working condition "just in case."
However, the oven is not the option that is able to warm up large areas of the house. Therefore, in order to achieve comfortable temperatures, in the building it was necessary to install several stoves that were shot several times a day. Of course, it is not only difficult, but also extremely uneconomically.
This discomfort is eliminated by creating a full-fledged heating system running from a solid fuel boiler of long-burning, allowing the whole house with warmth of one place. Unlike a conventional oven, such aggregates are able to work from one fuel laying up to 12 and even more hours. Thus, such a boiler will require attention twice a day, when the required amount of firewood is laid in the furnace.
By the way, there are also such models of solid fuel units that are capable of working on a single fuel and day bookmark, and more.
The advantage of solid fuel boilers is that almost all models can work not only on firewood, but also on other types of solid fuel. For this purpose, pellets, peat briquettes, as well as the so-called "EuroDrov" are produced from wood waste on an industrial scale.
As a fuel for these aggregates, some varieties of stone coal are used, however, not all models are designed for it. Therefore, if you plan to apply coal for heating, then you should choose the corresponding model, having studied its characteristics when purchased.
Design and principle of operation of heating boilers of long-burning
To figure out how the boiler is functions, as well as facilitate the process of its future service, it is necessary to familiarize yourself with the design and principle of work.
The principle of long burning is that, firstly, such boilers have a very voluminous firewood chamber. And secondly, that the combustion of fuel does not occur immediately, but as it were, it is broken into two stages.
- Firewood (or other solid fuel allowed for this model) is laid in the bracket chamber). This compartment must be filled almost to all its volume. Only the booty window is trying to lay out thin lanes, chips, branches, etc. - To facilitate the primary ignition.
- Next, with the help of rachin or paper, the fuel bookmark is ignition. At this stage, a sufficient amount of air is supplied to the chamber needed to occur intensive burning.
- After the fuel took, air supply to the chamber of this primary burning is minimized. Due to this, the usual active burning of firewood ceases and moves into the stage of thermal decomposition, in other words - strains.
- In such conditions, smoldering wood, with its decomposition, allocates very significant volumes of combustible gases with high energy potential. This process was called pyrolysis, and the gases themselves (in the composition of which prevails methane), respectively, are often referred to as pyrolysis.
- If in conventional furnaces, the resulting pyrolysis gases simply go into the chimney pipe, then in the long burning boilers, they enter the survival chamber of a special design. Here, under the influence of high temperature and excess oxygen supplied (air), the gas mixture is flammified, completely roars with a very significant heat release. As a result of the total cycle of firewood, there is practically no waste, since their solid component is destroyed to the smallest ash, and gaseous - intensively tramored in the survival chamber. This in the amount determines the high heat transfer of the boiler, its high efficiency.
It is the educated pyrolysis gases that are the main source of heat of thermal energy, and it is to the chamber of their survival there is a major part of the water circuit heat exchanger. Although, of course, the selection of heat begins in the primary combustion chamber.
Perhaps you will be interested in information about what characteristics has
To make it more clear how such boilers are approximately arranged, you can consider the following scheme:
1 - the boiler housing with a reliable layer of thermal insulation.
2 - Fire download window with a tightly closing door.
3 - the camera of the primary thermal decomposition of wood (pyrolysis).
4 is a roller in which impaired waste is going.
5 - channel dosage supply of primary air required to ensure firewood
6 - The feed channel of the secondary air required for the complete survivor of the elevated pyrolysis gases.
7 - Camera licenses of pyrolysis gases.
8 - nozzle for connecting the boiler to chimney to remove gaseous combustion waste.
9 - nozzle for connecting pipe-"return" of the heating circuit.
10 - nozzle for connecting to the feed of the heating circuit.
11 - an additional heat exchanger that is often used to connect to the boiler of indirect heating of the hot water supply system of the house
Of course, such a scheme is not at all some kind of dogma. The amount offered on sale models is large, and the layout can have very serious differences. In particular, the structure of the loading chamber, and the direction of combustion of the fuel laying, and the location and principle of the design of the secondary survival of pyrolysis gases can be distinguished. Each model has its own design of the "water shirt" or additional heat exchangers. But the principle of operation of the boiler still remains similar.
Before the start of operation of the selected model, it is necessary to carefully examine the scheme of its device, which is mandatory included in the documentation accompanying this heating device.

Varieties of structures of solid fuel boilers of long burning
Of the above information, it is already clear that the main task in the operation of the boilers of this design is to achieve the correct dosing of air flow: the primary entering the fuel cell, and the secondary air responsible for the quality full extension of pyrolysis gases.
In models of different manufacturers, these tasks are solved in various ways. That is, the design of boilers can be equipped with additional devices that balance the processes occurring.
Boilers with forced air supply
One of the design options are boilers with a fan embedded in them, which is used to injected air. The distribution of air flow across the internal channels is carried out using an automatic control unit.
Almost all boilers equipped with fans are condensed so that the main loading chamber is located in the central part of the structure.
Due to the presence of a fan, the fuel is quickly flared up, and the heat-resistant materials, which, as a rule, are lined with its inner walls (ceramobetone or shaft) perfectly accumulate heat. The traction created in the firebox constantly supplies the pyrolysis gas released by the fuel in the survival chamber, which in some models is located at the bottom. At the entrance, this space is installed special ceramic nozzles, withstanding the effects of temperatures reaching up to 1000 degrees.
Burning, pyrolysis gases heat the pipes of water "shirt". In turn, installed in the heating circuit and also associated with the automatic unit provides the required intensity of the movement of the coolant throughout the heating system.
In some models of solid fuel boilers, the survival chamber can be located in the rear or top of the boiler design.
If the survival chamber is located in the back of the boiler, it has a rather complicated design of heat exchange elements, which contributes to the rapid heat of the coolant. Due to this, a high efficiency of the device is achieved, sometimes up to 90 ÷ 95%.
Similar designs of electronic control boilers have a large number of advantages, but they have their own essential drawback - this is energy dependence. If the electricity is turned off, the fans, the pump, and naturally, the entire automatic block does not function, which leads to a suspension or complete stop of the coolant movement along the heating circuit. If the power outage is not uncommon for the area where the house is located, then it is necessary to have an autonomous power supply system - it can be an electric generator that must always be kept in a state of complete readiness. From infrequent and not too long interruptions help specially intended for this UPS - battery uninterrupted power supplies.
Another serious disadvantage of the boiler with an electronic control system is high sensitivity to voltage drops. Therefore, it is necessary to provide them with protection by installing a separate voltage stabilizer.
Voltage Stabilizer - Warranty of Copyright Boiler Electronics
Do not regret this device money - its cost is incomparable with the cost of a boiler saturated with electronics, and machining such a precautionary measure can pour out much more cost! How to pick up - read in a special publication of our portal.
Non-volatile heating devices
To avoid dependence on power stability, it is worth choosing long-term combustion units with the organization of natural air supplies and equipped with a mechanical control system. There are quite a few such models on the market. For example, it is familiar to all the boilers of the domestic manufacturer with the name "Bourges-K" or "Tray".
These devices have a bulk fuel cell located in the lower part of the design, under which it has pissed, simultaneously performing the asolnic function. The damper for air access located at the bottom of the door is connected by the chain with the thermostat.
When the firewood loaded into the firebox is, it is necessary to maximize the damper to ensure active fuel ignition and start the pyrolysis process. It requires a temperature of at least 200 degrees to achieve it.
After the fire, the damper should be closed, reducing to a minimum of oxygen access to the fuel cell, transferring the burning into the drainage stage. Further, as already described above, pyrolysis gases are released, which come and ignite in the survival chamber.
Thanks to this design, the heating device is completely non-volatile, so even in the absence of electricity, the house will still be equipped with heat.
Such type of boilers is inferior in its efficiency and saving fuel with energy-dependent devices, however, it is its independence from the presence of electricity makes it popular among consumers. In addition, you also do not have to pay for energy consumption, which will also help save on the operation of the heating system as a whole.
Solid fuel boilers with top burning
Another option of the design of heating units is the Orininal technological systems with the direction of burning firewood from top to bottom. A similar principle is used not only in many models of solid fuel boilers, but also in the furnaces working on the principle of long burning.
Boilers having upper ignition, as a rule, have a cylinder form located vertically. For this type of heating units, almost all types of solid fuel are suitable - it is firewood, briquettes, coal, chips, sawdust, etc. The camera in such boilers has a very large volume, which allows them to function on one fuel load for a long time: this duration depends on the specific Models and fuel type. For example, some of them are capable of working on firewood from 24 hours to three days, and when using coal - even from three to seven days.
The working cycle of such a boiler can be submitted in the following order:
So, such a boiler has a cylindrical vertically located housing (pos. 1).
Through a special door (pos. 2), the selected fuel is loaded (pos.3) into the chamber. At the bottom, the door is located (pos. 4), which serves to clean the camera from ash before the next load.
If firewood is used for heating, then large diameter lamps are stacked down and the middle of the bookmarks, and the chips are loaded around them. Then, with the help of paper, the upper thin firewood is ignition. To ignite fuel, you can use specially intended for ignition furnaces of liquid.
In the upper part of the case there is a channel of air supply (pos. 5) into the boiler, equipped with a valve. The catch can be manual or semi-automatic working on the principle of changing the configuration of the bimetallic plate under the action of temperature. The air from this channel enters the heating chamber (pos. 6), where he is heated under the action of the heat generated by the boiler.
As soon as the surface burning of firewood begins, a special air distributor is lowered to the bookmark (pos. 7). This is a rather massive part of a metal profile, inside which there are channels for a uniform air distribution over the surface of the burning fuel. With his weight, the distributor falls on the burning bookmark, and as it is gradually lowered downwards. For this, it is associated with the air heating chamber with a pipe of a special telescopic design (pos. 8).
In the heating chamber of the air there is a damper (pos 9), which adjusts the stream of secondary air into the upper part of the combustion chamber (pos.10).
Pyrolysis gases isolated when the top layer of the bookmark is raised into the upper part of the fuel chamber, where they are found with a hot secondary air flow. That is, all are created the necessary conditions For their complete survival with high heat release. After that, gaseous waste is discharged through the nozzle (pos. 11) into the chimney.
The heat generated is transmitted to the water shirt of the boiler (pos. 12), which through the nozzles "Frames" (pos. 13) and feed (pos. 14) are associated with the heating circuit of the system.
As you can see, in fact, in this design there is no obvious separation on the chamber of the preliminary burning of firewood and the final survival of gases - the total space is divided into these zones by the position of the air distributor, and the dimensions of these zones are changed along the operation of the unit.
Such patterns of boilers can be equipped with a built-in fan, which carries out air force forcibly. However, even their work can be carried out with only natural traction. Therefore, the home heating will work even in the absence of electricity.
This design has shown its effectiveness, so some homemade craftsmen take her base when creating their own products. A vivid example of this is a popular wood stove with an unusual name "Bunch".

Summing up - a few words about the advantages and disadvantages of wood boilers
So, despite the wide range of devices using other types of fuel, wood boilers Do not lose their popularity. Manufacturers constantly improve their products that complement them with innovative solutions that simplify the operation process and increase the efficiency of the aggregates. Due to this, many of the models may well compete with electrical and gas appliances.
Advantages Such equipment can be considered the following:
- Solid fuel boilers of long combustion have a high efficiency, which in some models reaches 95%, since due to the system of surviving the loss of the energy potential of the fuel used is almost minimized.
- The devices can be easily called environmentally friendly, as natural resources are used for their furnaces, emissions from which are well processed by plants.
- The autonomy of the work of most boilers make them independent of the presence of power supply.
- When installing the units of this type, there is no need to undergo long procedures to obtain various permits and coordination.
- Solid fuel boilers may have a two-circuit scheme that will not only damop the houses of the house, but also supply a family hot water. If this feature is not provided in the design of the unit, then the boiler of indirect heating is easy to connect it.
- These devices are designed for a very long service life, measured by decades. They are unpretentious in operation and maintenance.
TO disadvantages Solid fuel heating devices include the following factors:
- The devices require constant control of the work, as well as timely load of fuel into the combustion chamber.
- Mandatory cleaning of the fuel and ash chamber is required from the combustion products before the next job cycle.
- The need to arrange a high-quality ventilation system in a room where the boiler is installed, the well-thought-in design of the chimney.
- Almost all wood boilers have large dimensions, so they need to be equipped with a separate room or highlight enough space in one of the non-residential premises of the house.
- In addition, it will take an equipped place for storing solid fuel. Before each loading of firewood stored on the street should be listed for drying at a certain period. Too wet fuel will significantly reduce the efficiency of the boiler, since the pyrolysis process may be defective.

Overview of solid fuel boilers
In Russia heating boilers On solid fuel for long burning with an enlarged loading chamber are often used for private heating country houses. To the main disadvantage of such an option should be attributed to the fact that the power of the unit increases with increasing the length of the furnace, which can lead to its boiling in systems with a small amount of radiators due to their rapid heating. To avoid this in the system heating of private country house You must add one element - buffer container (tank battery). This container is filled with the coolant, it is established between the heating unit and heat consumers (radiators, warm floors, an indirect heating boiler). A buffer buffer bunch will not only increase the duration between bookmarks, but also reduce the cost of heating. The tank-battery is selected by a specialist, based on the system parameters, the heat loss of the house, the form of a fuel and the power of the aggregate. Capacitance litters can be calculated independently, taking the 1kW power ratio to 30-50 liters of the container.

GasHide aggregates
If we talk about modern solid fuel boilers of long burning, it is impossible not to mention about pyrolyasic instances. The principle of their action consists in the harrier of the wood gas released at the degeneration of combustible substances (called pyrolysis). For this, their design provides an additional second combustion chamber required for afterbill. Savings are obvious:
first, when he was consumed less resources;
secondly, when the pyrolysis products hit, the air is mixed into them, which leads to their combustion and contributes to additional heat release.
All this leads to an increase in the duration of work on one bookmark to 10-12 hours. It is important that with this process, the fuel resource is spent almost completely, which facilitates their cleaning, and most of the combustion products survive, which makes pyrolysis models more environmentally friendly.
The best heating boilers on solid fuel for long burning are often attributed to gas generator, as they are able to use wood, coal, sawdust and peat briquettes. However, it is worth noting that the highest efficiency is the use of wood with a humidity of less than 20%. Therefore, it must be prepared in advance, about a year before the start of operation.

The main disadvantages include:
- fans and other electrical components that exclude the non-volatility of such a purchase;
- the need for an elevator node or bandaged valve with a highly cooled heat carrier (to avoid such a situation and disruption of the pyrolysis process is heated by reverse water);
- restrictions in the use of firewood or coal with high humidity.
Models working on the principle of "top-down"
In order to understand the principle of operation of such equipment, it is enough to imagine a burning match. It burns significantly longer when the head is at the top. Here the situation is similar: the laid fuel resource is lit only in the upper layer. As the top layer is combined, the focus is lowered and lower. Equipment is two cylinders, between which the coolant is. In the inner cylinder, the fuel resource is combustion, the external cylinder is covered with thermal insulation.
Technical features And the characteristics of the boilers of heating on a solid fuel of long burning, working on the "top-down" principle, allow you to ensure the heating of the house on one bookmark to 24 hours. This is possible thanks to:
- large volumes from one load (compared to the classical solid fuel unit);
- layered adjustable burning;
- overall dimensions of a particular model.
If we talk about their advantages, it is primarily worth noting the automatic regulation of burning intensity, relatively affordable prices, as well as the ability to work without circulation pumps.
The main disadvantage is the inability to use bad wood or pellets, in particular with a humidity of more than 20%.

Equipment with automatic feed
Flowing over what kind of solid fuel boiler for long burning is the best, do not forget about the technology of automatic feed. This technique usually consists of:
- boot hopper;
- burners;
- pellet feed mechanism (auger);
- automation controls I.T.D.
For a century, pellets are tightly fed into the burner, where it is ignition and combustion. After the combustion of the first portion, the following is applied and so continues until the system comes to the specified temperature of the coolant. For them, pellets are used, less frequently fine coal. In Russia, pellet boilers have the greatest popularity.

Power and sizes
Before selecting a solid fuel boiler for long burning, it is necessary to pre-calculate necessary power Heating technology based on the square of the room, the thickness and height of the walls, the presence of insulation, etc. Also, this criterion is important for calculating the duration of work from 1 bookmark.
Type of fuel
Often both in industry and in everyday life:
- wood different types;
- coal;
- combustible slate;
- pellets;
- briquettes;
- peat.
In the process of selection, it is necessary to initially decide on the most priority option.
Heat exchanger material
Answering the question of how to choose a heating boiler on a solid fuel of long burning, do not forget about this criterion. Allocate 2 options: cast iron and steel. Cast iron is a sectional unit that has a lot of advantages. The only problem is exposure to thermal impacts.
Steel heat exchanger is a monoblock component that is less susceptible to thermal shocks, but has consumption during transportation and repair.
Economy
Each specific model has differences in service costs, maintainability, as well as in the efficiency. All this in the complex determines the efficiency of using a specific unit. On our site you can easily find detailed information about each model, as well as photo of boilers on solid fuel for long burning.
Durability of work
High-tech products from reliable manufacturers are able to serve at least 10 years. A huge role is played by the correctness of use and maintenance.
Let's start, naturally, with maximum power. No need to think that if the characteristics of the boiler is written "10 kW / 100 m2", then it is enough for a small house with a margin. First, the power of any solid fuel boiler depends very much on the quality of the fuel, besides, the characteristics indicated for coal (heat transfer above all). Try throwing the firewood - and at home it will immediately cool, well, and if the firewood also mock ... In addition, the boiler is greater power will have a larger firebox - and therefore it will be less frequent.
At all, the need for frequent addition of fuel is a common problem of solid fuel boilers. Solving ways are several:
- Bunker boilers - They are from a separate container (bunker) automatically "feed" the furnace. Such systems were developed primarily under pellets (fuel granules), which are very convenient to serve a screw, but now there are models capable of working on the corner.
- Boilers long burning have an increased loading volume, and the combustion process itself is not quite common - fuel is on top down. But they have no always convenient features - we wrote about it higher in the ranking.
But in any case, the "long-playing" boiler will become more difficult and more expensive, especially with the bunker. Whereas about combined boiler? In them, heating is provided not only by burning fuel, but also installed inside by ane - if the boiler goes out, electricity will continue to support at least some temperature. Such boilers are convenient to leave for the night - you will not wake up in the morning, feeling that the tooth tooth falls. Often to such boilers are offered and sets of retrofitting under gas or diesel fuel. In some models, it is even initially provided for automatic switching to liquid or gaseous fuel, if there is no fire in the furnace. In general, this option is interesting at least that when you appear the opportunity to connect the house to the gas, you don't have to change the boiler, buy a new, redo the connection: you can simply put the gas burner to the old one.
Important moment - design heat exchanger. Perfect option - cast iron: a thick-walled monolithic heat exchanger, if the manufacturer does not "penetrate" the shells and microcracks in the casting, will truly eternal, besides it will endure increased pressure without problems. But such a boiler will be more expensive (you can not fit into the budget), and harder (the question of the strength of the floor may have to strengthen it). Steel heat exchangers have the inevitable risk of leakage on welding, and the walls usually thinner. Therefore, it is worth at least taking a boiler, and the reviews for a specific model to watch before buying is true, and the reviews themselves have been buying a long time ago ... So choose a solid-splitting better go to the forums, and not on popular reviews for reviews that occupied paid praise.
Solid fuel boilers - an alternative method of heating of private houses. Electrical models Consume plenty of electricity, therefore the effectiveness of their application (especially on large areas) is very doubtful. Gas boilers In this regard, more justified, however, they require a supply to the home of the corresponding type of fuel, which is not always possible. It is in such cases that it is very difficult to overestimate the favor of furnaces, combustible material for which firewood, coal and other solid elements serve.
The current realities of the market are such that hundreds of potential consumers are presented, if not thousands, models of heating boilers for every taste: long burning and pellet, classic and pyrolysis. It is quite natural to make a good choice in such a situation very and very difficult. In order to simplify the situation a little, we have prepared a rating of the 18 best solid-fuel boilers of heating in six different categories.
The best solid fuel boilers for long burning
The advantage of heating boilers of long-term heating over others is clear from the title: The duration of the hard fuel extension in them with full loading of the firebox is two to three days, and in other cases (depending on the type of fuel) comes to five and even twelve days. At the same time, on an ongoing basis, the volume of thermal energy is distinguished, sufficient to heave the entire area provided. They are economical, however have a low efficiency and deliver a lot of trouble in maintenance.

2 STROPUVA MINI S8
The optimum ratio of price and quality. Select users
Country: Lithuania
Average price: 56 500 rub.
Rating (2019): 4.8
Lithuanian heating boiler highly appreciated by users. In essence, the Stropuva manufacturer continues and naturally reaps the fruit of the system built during the Soviet Union. The MINI S8 boiler is compact, made in the form of "barrel", but it is very hard for moving, in connection with which some problems arise with the installation. Its economy is connected, first of all, with the type - the long burning of one coal laying is capable of giving heat over two to five days. There are also no complaints about quality - everything is done reliably, carefully (that in the boilers is not so important) and causes some kind of true admiration. But one correspondence still has - shaggy cladding is practically not amenable to removing a car, which is most often formed above the furnace of the furnace.
Advantages:
- very high quality execution;
- efficiency in the heating of premises - one wood masonry is enough for 12-20 hours of burning; coal - up to five days;
- good balance price and quality ratio;
- the ability to connect additional contours, beans, and other systems.
Disadvantages:
- beautiful but impractical shaggy coating;
- the difficulty in movement associated with the large weight of the "mini-model".

3 Evan Warmos TT-18
High rated power
Country Russia
The average price: 32850 rub.
Rating (2019): 4.4
A solid fuel boiler of Russian origin. Not bad to become a source of heat for dacha houseBut dubious for use in the conditions of private space. All his trouble lies in the overestimated characteristics - the rated power of 18 kilowatt is designed for heating areas up to 120 square meters, but the effect of heat transfer is practically not felt. The real and most effective heating threshold is no more than 60 squares. Solid fuel, with optimal adjustment of the flaps, extends for 60-90 minutes, after which the boiler quickly cools and when you ignore this moment requires a re-extract. Yes, and about the functions of the Kochgar will not be able to forget. The result is natural: the model is quite "capricious", but if you wish, you can always find a compromise that arms both sides.
Advantages:
- very simple installation of the boiler;
- acceptable quality of the housing;
- can work on firewood, coal and peat.
Disadvantages:
- inflated data on heated areas;
- the need to select the optimal position of the flap to prevent the fuel recalculation or obstacles to normal burning.

16 Kilowatt Power of the Boiler Lemax Forward-16 is sufficient for heating the premises of administrative and household levels, private residential buildings and even cottages, by independent or forced (with the pump installation) circulation of the heat carrier on the heating water system. This is one of the most successful examples Small, but productive installations that have uncharacterically high (about 75-80 percent) The level of the efficiency. The uncomplicated design contains the solution of many problems of operational nature. From the point of view of the technologist, such measures, such as the "chipping" of the heat exchanger of chapellers to increase the limit resistance to the gap, look excessive but justifying themselves from the durability of use. Such a boiler is able to serve good seven-nine years, provided that everything is complied with the right operation, without exception.
Advantages:
- the presence of additional elements that have a positive effect on the durability of the installation;
- optimal cost when acceptable quality;
- high enough (atypical) PDA level;

Protherm Beaver 50 DLO is a real monster among the elite, the product of Slovak production, which will definitely have to do with each who wishes to have a high-performance heating boiler.
Slovaks did not come up with anything new to preserve useful thermal energy. Based on the well-known physical laws, facts and practices, they simply blurted under the cast iron case, thermally insulating glass wool, thereby reducing thermal losses. As a result, the simple step of the efficiency took off to the crazy 90 percent. By updating the standard form of heat sinks, they can increase the combustion chamber volumes. Thus, from one load, you can catch up with a completely comfortable temperature to the room with an area of \u200b\u200bup to 350 squares. This largely contributes to the rated power of 39 kilowatts.
Advantages:
- high technical characteristics;
- appropriate assembly quality;
- extensive heated area;
- low thermal losses due to the presence of insulating material;
- the presence of a air regulator;
- the presence of a service tool.
Disadvantages:

High PDA (91%)
Country: Austria
The average price: 370216 rub.
Rating (2019): 4.8
Austrian boiler capable of maintaining a comfortable temperature for a whole day. It all depends on the selected power: in the nominal mode of burning firewood and briquettes is no more than four hours. With a decrease in the indicator, the speed of complete combustion of the bookmark decreases. According to experts, an important difference between this model from domestic is the flow of the present process of pyrolysis, in contrast to ordinary fruzhigi. Perhaps the only drawback of the boiler is the need for a constant connection with CAS - a specialized heat-battery tank. The operation of the systems is responsible for the control panel.
Advantages:
- the presence of a control panel is a complete automation of processes;
- after pyrolysis, the process of exhaust gases occurs - complete fuel generation;
- high rated power.
Disadvantages:
- the failure of the control panel is deprived of the user manipulation of processes;

Best Nominal Heavy Power (36 kW)
Country: Czech Republic
The average price: 171900 rubles.
Rating (2019): 4.9
Pyrolysis of a major European level, created in all current quality standards. Czech manufacturers decided to release the range of installations with automatic controls than simultaneously facilitated and complicated their lives and users. The fact is that "automation" is a delicate thing, and in some particularly unfavorable cases (due to incidents) can easily fail. Repair and commissioning of the control system on the boiler of this level is expensive, which often causes the perplexity and angry reaction of people. Perhaps this is the only significant disadvantage of the system, because in the rest of the components it is almost perfect.
Advantages:
- the presence of the automatic control system with temperature and regime parameters;
- the presence of emergency, boiler and boiler sensors;
- the burning of the sword of wood is 12 hours, briquettes - 15-17 hours;
- high-quality assembly materials;
- extended complete base.
Disadvantages:
- adjustment and repair automatic system Control, in case of failure, will fly away to the consumer in a penny.
The best solid fuel boilers pellet type
Pellet boilers are dimensional installations equipped with hoppers for granulated wood waste. The dimensions of such granules range from 5 to 70 millimeters in length and from 6 to 10 millimeters in thickness. This is the longest way to heating the room. The duration of heating directly depends on the volume of the adjacent bunker, and can be 2-12 days. The main drawback of such boilers is deficit fuel. Granulated pellets are not sold everywhere, therefore the probability of idle equipment is great.
3 Zota Pellet 100A

Country Russia
The average price: 379000 rub.
Rating (2019): 4.9
One such boiler is more than enough for the heating of a whole building, where there is a water heating system with a pre-installed pump for forced circulation. Manipulation by all aspects of the system is reduced to the electronic control panel. This system is truly insensitive - unless, of course, before the user is not worth the reverse target. The rated power of the boiler comes to 100 kilowatt, but it can be reduced by regulating air supply. In the same way, pellets in the furnace are also adjusted. The only and most significant disadvantage of the system is overweight design. 829 kilograms - exactly so much weighs this unit, which is not so easy to move even within the delivery task, not to mention the final installation.
Advantages:
- the price corresponds to the declared parameters;
- fuel supply to the combustion chamber is carried out by a screw mechanism;
- the electronic control system controls all aspects of the functionality of the installation;
- high rated power.
Disadvantages:
- very big weight design.

- not the highest efficiency (75%).
Gasification of private sectors goes with seven-mile steps. But still many settlements are honeble with coal or firewood. And when the "blue fuel" will come to them unknown. But the budget is not rubber. Looking at the growing prices for firewood, coal or pellets (extruded fuel) people grab the head. However, from the situation there is a yield - solid fuel boilers of long burning with water circuit, saving and firewood, and time. You need to trample once a day, and some models have enough once a week. Today we'll figure it out what it is for the "miracle aggregate" why it is so rarely needed to trample and how much such a boiler costs.

Solid fuel boilers for long burning with water contour: advantages and disadvantages
Solid fuel boilers of long burning for heating is an opportunity to provide a dwelling with warmth and create comfortable conditions For life, spending a smaller amount of firewood or coal at the same time than it happens when using a conventional oven. Such an aggregate has a lot of advantages, among which it is worth highlighting:
- efficiency achieved by a high efficiency;
- the unit is easily serviced;
- low cost;
- ecology and safety.
Depending on the model, such aggregates can be equipped with additional options that will facilitate the heating process. However, it is not necessary without drawbacks, among which it is worth noting the need for periodic cleaning and fuel loading (in comparison with gas and electric equipment). But these shortcomings disappear if you compare a device with conventional furnace heating.
Principle of operation of the boiler on solid fuel for long burning
The principle of operation of a solid-fuel boiler for home heating is based on the properties of wood, to allocate gas in combustion, called pyrolysis. In a wood-burning furnace, this gas is not used by a constructive reason. He himself is fuel, which in combustion gives a large amount of heat. Using pyrolysis gas, engineers managed to increase the efficiency of the heating boilers on a solid fuel of long-burning due to the minimization of an open flame.
Classification of aggregates: what to pay attention to when choosing
The choice of a long burning boiler depends on several factors. The weight of the equipment is taken into account, but only if the device is placed on the wall. The main attention is paid to the basic parameters. To determine them with them, consider the classification of aggregates.
Fuel combustion method: what better
There are two types of devices - energy-dependent and non-volatile. Consider their differences, pros and cons.
A traditional energy-dependent boiler is comparable to a conventional stove, which has a window in the upper part. Fuel is loaded into it. Firewood or coal is stranded, there is no open flame, but it is enough to highlight this heat. At the same time, a special fan periodically turns on, removing excess oxygen from the furnace. Due to the absence of an open flame, a fuel economy is achieved and the time interval between its bookmarks increases.
Such an unit is equipped with a surge chamber that provides an increase in efficiency to 80 ÷ 85%. These devices are reliable and durable due to the simplicity of the design, but have a drawback - energy dependence. When the electricity is disconnected, the fan ceases to turn on and does not occur. The access will be the acquisition of the UPS (uninterruptible power supply).
What is a pyrolysis solid fuel boiler
Pyrolysis call non-volatile devices. The difference from the previous version is that the fuel is first dried, after which degassing occurs. As a result, more than 80% of substances are converted to gas, the combustion temperature of which is 2 times higher than that of wood. To understand the principle of work, we suggest to watch a short video:
Advantages - efficiency (up to 95%), efficiency and autonomy (power outages are not terrible).
What type of fuel to choose
An important parameter for family budget saving is a type of fuel that the unit will use. The choice here will depend on what is more profitable to purchase in a region or another. If a person lives there, where many forests, naturally, he will choose a boiler on firewood. But it is worth noting that the long-burning boilers on the corner require the bookmark less frequently than wood.
Number of contours: how important this parameter is
The choice of this parameter depends on the presence of hot water supply in the house. Double-circuit devices are more expensive, but it is possible to organize a DHW in the home in addition to heating. If there is no hot water in the house, this factor is crucial, especially if small children live in the house.
Important! An additional circuit makes it possible to uninterrupted hot water supply only in the presence of cold. If there is no water supply in the house, there will be no sense from the overpayment.
Select the device for heating by power
The power of the unit determines the ability to heat the specified area of \u200b\u200bthe room. Nothing difficult. We get more expensive and no problems. But the question arises, why overpay for unnecessary power? Yes, and fuel on such equipment leaves more. The reverse side of the medal is insufficient power. In this case, the equipment does not warm the room to a comfortable temperature - and again the money thrown into the wind.
In order not to make a mistake with the power of the boiler on solid fuel, we offer to use the online calculator. It will eliminate the error in the calculations that a person can allow. All that is required by the user is to make data into the appropriate fields and click the "Calculate" button. The program will display the necessary parameter of the equipment in kW.
